Abstract (en)
[origin: EP2337034A1] The invention relates to nuclear reactor elements, in particular to the structural design of spacing and mixing grids of fuel assemblies. The mixing grid comprises a hoop and a set of intercrossing plates which form a field of cells for accommodating fuel elements and the supporting elements of the fuel assembly. The cells for accommodating the supporting elements have a circle cross-section. The cells for accommodating fuel elements are hexahedral and the cells for passing a coolant which are adjacent thereto are trihedral. Two faces of each trihedral cell are concave, the third face being provided with a plate deflector
